Unified transaction services for multi-tenant architectures

ABSTRACT

A method for using unified transaction services in a multi-tenant architecture system is discussed. The method includes receiving a request, at a first service provider, to provide a first transaction service for a user. The method includes accessing a first representation of the first service provider in a first hierarchical data structure, the first hierarchical data structure being managed by a second service provider, the second service provider managing user identity of the user. The method includes determining, based on the first representation, that transaction resources required for completion of the first transaction service are provided at the second service provider using a resource representation. The method also includes, responsive to determining that the transaction resources are accessible at the first service provider, accessing, at the first service provider, the transaction resources via the resource representation.

This application claims the benefit of and is a continuation-in-part of U.S. application Ser. No. 16/009,994, titled “Unified Identity Services for Multi-Tenant Architectures,” filed on Jun. 15, 2018, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

Embodiments of the present disclosure generally relate to the field of software architecture and, more particularly, to managing how various entities are on-boarded, managed, and/or accessed in a multi-tenant system architecture.

Complex software systems can have various architectures, including a single-tenant software architecture and a multi-tenant software architecture, among others. In a single-tenant software architecture, each entity (such as a company or a portion of that company) can have their own instances of each software application, data, and any supporting infrastructure. In a single-tenant architecture, the software for each tenant entity can be customized as desired. However, drawbacks of using the single tenant architecture include expense in resources, as well as requirements to host, customize, and maintain separate software applications for each tenant.

In contrast, in a multi-tenant software architecture, each entity can share the same instances of applications, data, and/or infrastructure. A multi-tenant software provider can provision their applications and/or resources to multiple entities from a single software architecture. In multi-tenant software architecture, access to data can be shared among the various entities. By sharing much of the applications, data, and software, various resources such as installation, configuration, number of physical servers, maintenance, and even power can be optimized. However, drawbacks of using multi-tenant architecture include complexity of managing how multiple software applications are configured and shared among multiple clients. Also, design of multi-tenant architecture-based software systems that provides secure and reliable access to the data, resources, and/or transaction services that operate using the data and/or resources can be problematic. Furthermore, interoperability difficulties may arise when using software applications, in a multi-tenant architecture system, that were initially managed and/or hosted by different businesses.

DESCRIPTION OF EMBODIMENT(S)

The description that follows includes exemplary systems, methods, techniques, instruction sequences, and/or computer program products that embody techniques of the present disclosure. However, it is understood that the described embodiments may be practiced without these specific details. For instance, although some examples refer to accessing tenant services, other types of service providers are contemplated, such as of Software-as-a-Service (SaaS), among others.

In a multi-tenant software architecture described herein, each tenant can share the applications, data, and/or infrastructure. A multi-tenant software provider can use a multi-tenant software platform to provision applications and/or resources to multiple entities. The multi-tenant software platform can facilitate addition of new tenants and on-board data and/or services provided by these new tenants. The multi-tenant software platform can implement rules and policies for data access by various entities across the tenants. The multi-tenant software platform can use identity services to provide access to these services, such as from an entity associated one tenant to a service provided by another tenant. The multi-tenant software platform can facilitate transaction services between tenants, such as a transaction service originating at one tenant that accesses resources at another tenant.

The multi-tenant software platform (also referred to as a multi-tenant platform) can include multiple tenants that have been previously on-boarded. The multi-tenant platform can facilitate access, using a unified identity associated with a user, to the entities, policies, and services of these tenants. The tenants can be hosted and managed by service providers. Access to the services can be determined based on privileges of the unified identity, as well as on policies of each of the tenants. The services can include various merchant services, such as in-store check-out (at a certain tenant) via a user device (associated with the unified identity), access to an online store of the tenant, order-ahead at a certain store of the tenant, a cash-in process (e.g., at an Automated Teller Machine (ATM)) at a certain tenant, a cash-out process (e.g., at an ATM), self-checkout for fuel at pay-at-the-pump stations of the tenant, among others.

The services can include SaaS and Platform as a Service (PaaS) services and/or other cloud services that are accessible by the user device. For example, the solution provider can provide access, to the user device, to various software applications, or deliver such software to the user device. The services can also include inter-tenant transaction services, where a transaction service that is originated at a first tenant needs to access transaction resources at a second tenant. The multi-tenant platform can access other services, such as multi-tenant identity services, multi-tenant social graph service, and/or multi-tenant transaction resource service to determine how to process a certain inter-tenant transaction service.

The multi-tenant platform can thus utilize unified identity services to provide access to selected services and/or data of the tenants based on policies associated with each of the tenants. The multi-tenant platform can use separate databases to store data to achieve isolation, such as when new tenants are on-boarded onto the existing platform, and to provide logical and/or physical data isolation. Shared data access can be made possible by on-boarding the tenants and selectively cross-exposing services. For example, for a multi-tenant platform managed by PAYPAL, certain capabilities of the multi-tenant platform such as Risk-as-a-Service (RaaS) and/or TRaaS (Transaction Resource as a Service) can be provided to certain users of on-boarded tenants such as XOOM. Similarly, certain capabilities of XOOM such as Fund Sending can be provided to certain users of PAYPAL. Thus, in some embodiments, the multi-tenant platform can include a core tenant (such as PAYPAL) that offers core services and infrastructure (including Identity-as-a-Service (IaaS) functionality and TRaaS) and any additional data access to selected tenants and/or users accessing the multi-tenant platform from that tenant. The level of access to the core services and/or infrastructure can be determined by rules and/or policies of each tenant and/or of the multi-tenant platform.

The multi-tenant platform can onboard new tenants by using a one or more hierarchical data structures. In some embodiments, the multi-tenant platform can expose appropriate user experiences for a user application based on the user request. The multi-tenant platform can implement methods for providing IaaS services to various entities and/or tenants. The multi-tenant platform can provide the IaaS and other services based on the hierarchical data structures. As discussed below, the multi-tenant platform can process user requests (e.g., from users of the core tenant or from users of an on-boarded tenant) and determine how to access and process services, including inter-tenant services.

In some embodiments, the multi-tenant platform can receive a request, at a first service provider, to provide a first transaction service for a user. The multi-tenant platform can access a first representation of the first service provider in a first hierarchical data structure that is managed by a second service provider, where the second service provider manages user identity of the user. The multi-tenant platform can determine, based on the first representation, that transaction resources required for completion of the first transaction service are provided at the second service provider using a resource representation. The multi-tenant platform can, responsive to determining that the transaction resources are accessible at the first service provider, access, at the first service provider, the transaction resources via the resource representation. The following description and associated Figures illustrate various embodiments directed to the ideas listed above.

FIG. 1 is a system diagram illustrating embodiments of a multi-tenant software architecture system that can be accessed by communicating with a user device. In an overview of the system diagram, a user device 104 can communicate with a processing system 100 that includes a multi-tenant platform 102. The processing system 100 can process requests using a multi-tenant transaction processor (mt-transaction processor) 101. The multi-tenant platform 102 can provide access to multiple service providers 108, 110, and 112. In some embodiments, the multi-tenant platform 102 can model each of the service providers 108-112 such that the mt-transaction processor 101 can access services 116-124, policies 123-127, and/or resources 162-166 of the service providers.

The multi-tenant platform 102 includes core services at elements 132-148, as well as additional services 130(1)-130(5). The multi-tenant platform 102 can provide services to the service providers 108-112, such as IaaS services that may be required for accessing other services. Thus, the multi-tenant platform 102 can manage a plurality of tenants, each one of which can be associated with one or more services, which are then exposed for access. In some embodiments, each of the service providers 108-112 can be the actual providers that are then represented (e.g., by modeling) in the multi-tenant software architecture (i.e., in the multi-tenant platform 102). Although not shown in FIG. 1, each of the service providers 108-112 can include a respective transaction processor for processing own requests. The mt-transaction processor 101 can be a transaction processor that was fully integrated onto the multi-tenant platform 102. The mt-transaction processor 101 can be a default transaction processor for processing transactions.

The multi-tenant platform 102 can store user information for users at the accounts 142. In some embodiments, the accounts 142 includes information for users (also referred to as “core users”) of a core tenant. The core tenant can be one of the service providers 108-112, or a service provider that is fully integrated into the multi-tenant platform 102. The multi-tenant platform 102 can facilitate provision of various core services to the core users. The core services can include identity services 132, risk services 138, compliance services 140, and payment services 148. In one embodiment, the multi-tenant platform 102 provides IaaS services at the identity services 132 element. The identity services 132 can generate and maintain a core hierarchical data structure for managing its core entities. The core services can also include access to policy configuration 136, as well as access to accounts 142, merchants 144, and consumers 146. The accounts 142 are associated with the identity services 132. The multi-tenant platform 102 can also provide inter-tenant transaction services, such as between tenants 108 and 110, where the tenants 108 and 110 need not be fully integrated.

The processing of a certain transaction can be initiated by the mt-transaction processor 101 by using a single instance of an MT-IDP (such as the MT-IDP 246 discussed below) to access resources (as required by the transaction) at a certain service provider. In one example, the processing system 100 can process a transaction service that is requested at the service provider 108. For example, the mt-transaction processor 101 can use the multi-tenant platform 102 to process a request that is received from the service provider 108 for use of certain transaction resources, which can be provided by the multi-tenant platform 102 and/or by other service providers 110-112. These transaction resources can be accessed, at the multi-tenant platform 102, via a resource representation. The multi-tenant platform 102 can access the identity 132 services, transaction resource service 150 (referred to also as MT-FI 150), and/or the social graph service 160 (referred to also as MT-SG 160) to determine the resource representation.

The service provider 108 can include entities 114, policies 123, services 116, and transaction resources 162. Similarly, the service providers 110 and 112 include entities 118 and 122, policies 125 and 127, services 120 and 124, and/or transaction resources 164 and 166, respectively. The elements 114, 123, 116, and 162 of the service provider 108, and similar elements of the service providers 110 and 112 can be modeled by the multi-tenant platform 102, as discussed below. The multi-tenant platform 102 can determine how transaction resources (for a certain transaction) are being provided, such as by redirecting the request to use actual transaction resources that are hosted by one of the other service providers 110 or 112. For example, the actual transaction resources at the service provider 112 can be accessed by the mt-transaction processor 101 through the multi-tenant platform 102 via the resource representation. The multi-tenant platform 102 can thus facilitate processing of transactions using a unified multi-tenant architecture for transactions (i.e., service transactions) that originate at one tenant and use resources at another tenant. As discussed below, the multi-tenant platform 102 can determine to use another transaction processor (e.g., an actual transaction processor of the service provider 110) for processing of the transaction.

In some embodiments, a certain service provider can be fully integrated onto the multi-tenant platform 102, a process which can include generating the core hierarchical data structure for the core tenant. In this example, the identity services 132 can manage the core users (e.g., in its own namespace), meaning that the service provider 108 does not have its own identity service for its own users. The service providers 108, 110, and 112 can be on-boarded onto the multi-tenant platform 102 and manage their own identities. Any access from the service provider 110 for access of a service other than its own services 120, such as access of a service 130(1), uses a unified identity for access of services and/or data across the multi-tenant platform 102. In one example, the multi-tenant platform 102 can process a request that is received at a fully integrated tenant (e.g., at the multi-tenant platform 102). The request can be for a transaction service that uses the transaction resources 164 at the service provider 110.

In some embodiments, the mt-transaction processor 101 can access, via the resource representation, a modeled resource as modeled by the multi-tenant platform 102. The multi-tenant platform 102 then can facilitate access to the actual transaction resource that is associated with the modeled resource. Thus, the actual transaction resources 166 at the service provider 112 can be accessed by the mt-transaction processor 101 through the multi-tenant platform 102 via the resource representation. The actual transaction resource at the service provider 112 can be consumed. For example, the actual transaction resources 166 can correspond to a certain a financial instrument that is on-boarded by the service provider 112. The actual transaction resources 166 can correspond to incentives that are associated with the user's account. In another example, the actual transaction resource 166 can correspond to certain memory and/or computing resources (e.g., for a certain requested SaaS transaction). Upon processing, a value of that transaction resource at one tenant can be changed, such as decremented from one value to another value (and potentially incremented at another value of another transaction resource at another tenant).

The multi-tenant platform 102 can onboard the service providers 108-112, such as to generate models of the respective service provider(s). As discussed below, the onboarding process can include accessing identity services to determine at least a portion of the entities that are being managed by the respective identity service. If the entities are not being migrated (e.g., by being fully integrated) to the identity services 132, then the identity services can generate representations of the entities being on-boarded in the core hierarchical data structure. These representations are then being used by the IaaS service to determine and use the unified identity (for a certain user) across the multi-tenant platform 102. The representations can include lightweight elements and/or linked elements. The identity services 132 can manage and access the policy configuration 136, such as to enforce access to certain customer and/or merchant domains. The policy configuration 136 can be accessed via the hierarchical data structures (discussed below) for each entity. The process of generating and using user representations is explained in more detail below.

The multi-tenant platform 102 can communicate, via the multi-tenant API 126, with the service providers 108-112 and/or the user device 104. The multi-tenant platform 102 can provide, based on a certain unified identity, information related to a tenant, associated services, and/or associated user experiences, to a requesting entity via the multi-tenant tenant API 126. Furthermore, the multi-tenant platform 102 can facilitate communication between various tenants 108-112, such as by providing IaaS services and use of unified identity.

For example, a new tenant, such as the service provider 112, can be on-boarded by the multi-tenant platform 102. Information on the new tenant can be stored by one or more of the core services 132-148. In some implementations, upon onboarding, a namespace (e.g., its entities such as merchants and/or customers) that is associated of each tenant can be onboarded onto the identity services 132. In some embodiments, one or more of services of the new tenant, such as the service 124, can be exposed for access to other users of the multi-tenant platform 102. In one embodiment, the multi-tenant platform 102 can also generate a representation 130(5) of the service 124 at the multi-tenant platform 102. Thus, any access from other tenants, such as from the user device 104 or from the service provider 110), to the service 124 is performed via a unified identity (e.g., by using IaaS) at the service representation 130(5). In some embodiments, for onboarded tenants that are fully integrated, access to services of that tenant can be performed by the mt-transaction processor 101 directly, without using representations of the fully integrated service. In some embodiments, for onboarded tenants that are not fully integrated, access to services of that tenant can be performed by the mt-transaction processor 101 by calling the representation 130(5) of the onboarded (but not fully integrated) service. The representation 130(5) can then access the actual service 124.

The user device 104 can be any type of a computing device that can communicate user requests to the multi-tenant platform 102. The user device 104 can be implemented as a kiosk, a point-of-sale (PoS) terminal, a mobile device, among others. The user device 104 includes a user interface (UI) 106 through which the user can interact with displayed user experiences, such as to access certain services provided via the multi-tenant platform 102. The user device 104 can generate and communicate a user request for a certain service at the multi-tenant platform 102. The user device 104 can interface with the service provider 108-112 and/or with the processing system 100. The transaction processor then can communicate with various components of the multi-tenant platform 102, such as via the multi-tenant API 126.

In some embodiments, one of the tenants 108-112 can implement one or more payment system functions. In one embodiment, the core service provider (that is integrated into the multi-tenant platform 102) can process a payment and order fulfilment for services provided via user experiences accessed at the UI 106. The core service provider can perform risk analysis (e.g., via the Risk core service 138) to determine whether to perform a certain service and/or process a payment for that service. In some embodiments, the core service provider can perform risk and/or verification services for the new tenant 112 being on-boarded by the multi-tenant platform 102. The core service provider can process payments from the user account that is associated with the user device 104. The core service provider can provide financial services, such as a fund transfer (e.g., a transfer of a certain monetary amount), to the user. The core service provider can include payment accounts, each of which can be associated with a buyer or a seller.

Once on-boarded as a core tenant, the accounts of the core service provider can be stored and accessed directly at the multi-tenant platform at the accounts 142 element. For example, a buyer (e.g., a user of the user device 104) can be associated with one payment account, and the seller (e.g., one of the tenants) can be associated with another payment account at the payment system (which can be implemented using the processing system 100). Upon successfully performing the risk analysis on the requested service (e.g., a requested transaction at the tenant), the core service provider can then perform (e.g., via the payment core service 148) a fund transfer from the buyer's payment account to the seller's payment account.

The payment system can be implemented by PAYPAL or another online payment system that allows users to send, accept, and request fund transfers. In some embodiments, the user experience can also provide access to certain services. Thus, in addition, or instead of, a payment service, the user experience can include other functionality that is unique for the certain tenant, such as selection of items for order, access to certain SaaS functionality, among others. Thus, the solution provider can provide funds in/funds out services, as determined based on the location data, from the payment system to the users of the user devices.

For simplicity, FIG. 1 only shows a single user device 104. However, as discussed herein, the multi-tenant platform 102 interfaces with multiple user devices, and thus provides access to services to many different users. Similarly, the multi-tenant platform 102 can onboard multiple tenants in addition to the ones shown. The multi-tenant platform 102 can also have multiple core tenants that are incorporated as part of the core services 132-148.

FIG. 2 is a system diagram illustrating embodiments of the multi-tenant software architecture of FIG. 1 including unified transaction services. FIG. 2 shows embodiments of how the identity services of the service providers 108 and 110 are modeled by the multi-tenant platform 102. As shown, the (actual) service provider 108 can include a third-party identity provider (3P-IDP) 204 that manages entities of merchant 206(1) and 206(2), and entities of consumer 202(1) and 202(2). Similarly, the (actual) service provider representation 110 can include a 3P-IDP 204 that manages entities of consumer 214(1) and 214(2). In some examples, prior to being on-boarded, the service provider 108 is operable to can perform services 116 (optionally based on the policies 123) for the entities 114 using the resources 162, without using the multi-tenant platform 102.

The multi-tenant platform 102 includes the identity service 132, the accounts 142 element, the risk 138 element, as well as services 130(1) and 130(2). The multi-tenant platform 102 also includes the identity service 132, the accounts 142 element, the risk 138 element, as well as services 130(1) and 130(2). The service provider 108 can be modeled by the multi-tenant platform 102 by the identity service 132, e.g., as part of the hierarchical data structure 244. As discussed below with reference to FIGS. 3-5, the identity service 132 can model some parts of the service provider 108, including the 3P-IDP 204, the merchants 206(1) and 206(2), the consumers 202(1) and 202(2), and/or the FIs 209(1) and 209(2). The identity service 132 can similarly model some parts of the service provider 110 and/or other service providers. The identity service 132 can model each of the service providers 108 and/or 110 as service provider representations that can be generated during onboarding of the respective service providers 108 and/or 110. The 3P-IDPs 204 and 212 can be represented, in the hierarchical data structure 244, of the actual IDPs provided by the service providers 108 and 110, respectively.

The identity service 132 includes an access tier 242 and the hierarchical data structure 244 that is managed by an MT-IDP 246. The multi-tenant platform 102 also includes services 138, 142, and 130(1)-130(2). The access tier 242 is a part of the identity service 132 that customizes data associated with the service provider when being on-boarded with the multi-tenant platform 102. For example, the access tier 242 includes information about the products and/or services being offered by the service provider 108, as well as service endpoints for accessing services (e.g., the service 116) offered by the service provider 108. The service endpoints can be referenced by a corresponding node in the hierarchical data structure 244 that represents the service provider 108.

Various embodiments of how the hierarchical data structure 244 is generated and accessed are discussed below with reference to FIGS. 3 and 4. The MT-IDP 246 can generate and manage representations of the entities of the onboarded tenants, i.e., entities 206(1), 206(2), 202(1), and 202(2), as well as the 3P-IDP 204 of the service provider 108. Similarly, the MT-IDP 246 can generate and manage representations of entities 214(1), 214(2), 212 of the service provider 110.

Since each of the service providers 108 and 110 includes own 3P-IDP 204 and 212 respectively, each of these tenants can continue to manage the identities of their own respective entities. For example, the service provider 110 can continue to manage the entities 214(1)-214(2), including managing identity information, contact data, and any characteristics of the consumers 214(1) and 214(2). The service provider 110 can update any changes to the entities 214(1) and 214(2) to the multi-tenant platform 102, such as via a representation of the 3P-IDP 204 in the hierarchical data structure 244. These 3P-IDP 212 originated updates are used to keep the data of their respective representations up-to-date. Similarly, any services (such as core services) performed via the representations of the hierarchical data structure 244 can be propagated back to the 3P-IDP 212.

The transaction resource service 150 (referred to also as MT-FI 150) can include a resource access tier 252 and a hierarchical data structure 254 that is managed by an FI-IDP 256. The resource access tier 252 can customize resource data associated with entities of the service provider when being on-boarded with the multi-tenant platform 102. The resource access tier 252 includes information about the resources 162 that is associated with each one of the entities of the respective service provider, such as resources associated with the consumer 202(1) and/or resources associated with the consumer 214(1). The resource access tier can also include information about transaction services being offered by the service provider 108, as well as service endpoints for accessing the transaction services that use the resources 162. The service endpoints can be referenced by a corresponding node in the hierarchical data structure 254. In some embodiments, the resources can be implemented as funding instruments, e.g., for the consumers 202(1) and 202(2).

Similarly, the social graph service 160 (referred to also as MT-SG 160) can include a social access tier 262 and a hierarchical data structure 264 that is managed by an SG-IDP 266. The social access tier 262 can customize social data associated with the entities of the service provider when being on-boarded with the multi-tenant platform 102. The social access tier 262 includes information about links between each of the consumers, such as consumers 202(1), 202(2), 214(1), and/or 214(2). The social access tier 262 can also include service endpoints for accessing various social media applications based on which the hierarchical data structure 264 is generated.

In some implementations, the multi-tenant platform 102 can enable co-ordination of multiple identity namespaces (e.g., separate namespaces associated with the service provider 108, the service provider 110, as well another namespace associated with the fully integrated service provider of the multi-tenant platform 102) to efficiently and securely transfer transaction resources between identities corresponding to entities of these namespaces. For example, a user in one domain (e.g., a namespace associated with the service provider 108) can, via the multi-tenant platform 102, lookup users in other namespaces (e.g., a user in a namespace associated with the service provider 110, or a merchant associated with the service provider 112) and establish a relationship including transaction resource transfers.

In some embodiments, a user (e.g., a customer) can onboard as an entity to any of the service providers 108-112. In one example, the user can onboard onto the service provider 108. As the service provider itself is a tenant in the multi-tenant architecture 102, a representation of the user would be created by the identity services 132 (such as under a 3P-IDP representation for that tenant representation in the hierarchical data structure 244). That 3P-IDP can be indicated as a system-of-record (SOR) for that onboarded user. Once the user has onboarded, the transaction resources (e.g., funding instruments) for the user would be managed by the MT-FI 150. The user can add/remove transaction resources 162 by accessing the service provider 108, which would be reflected by the MT-FI 150. The multi-tenant platform 102 can identify the user in the namespace for the service provider 108, and can also associate (via the identity services 132) that user with the same user in another namespace (e.g., in the namespace for the service provider 110). The multi-tenant platform 102 can use the identity services 132 to identify the same user and his/her transaction resources across various namespace, thus enabling the same user to have multiple accounts in different namespaces and potentially linking or federating these accounts.

In some embodiments, during the onboarding process for a new tenant, there is a phase of tenant Setup where entities (e.g., consumer representations of the actual consumer, linked consumer for VENMO (e.g., the service provider 108) consumer under VENMO tenancy are modeled with specific policies set for the tenant. When the tenant (e.g., VENMO) gets its credentials (client identifier and secret) from the multi-tenant platform 102, the credentials can include appropriate Access Token and/or Refresh Tokens. These tokens can indicate embedded tenant information. When the tenant calls into the multi-tenant API 126, the multi-tenant platform 102 can authorize the request and convert the Access Token into a Security token.

When transaction resources are on-boarded onto the MT-FI 150, the tenant identifier can be used by the MT-FI 150 and the associated details can be retrieved from the security context (of the security token). In some embodiments, some details around the tenant and the associated accounts can be inferred from the Access Token and the translated security context after validation/verifications from the identity services 132. Thus, when a new Venmo user account is generated, the identity services 132 can create a representation of that account in the hierarchical data structure 244, and associated funding instruments for that user can be added to the MT-FI 150.

FIG. 3 is a diagram illustrating embodiments of flow of operations of using the multi-tenant software architecture for unified transaction services. FIG. 3 illustrates a logical view of how transactions are processed between service providers 108 and 110 using the mt-transaction processor 101. In some embodiments, any one of the service providers 108 or 110 can receive a request 302 to provide a transaction service to a user. The service provider 108 includes resources 162. In some embodiments, at least a portion of the resources 162 (e.g., for certain users of the service provider 108) can be associated with certain elements of the resources 164 at the service provider 110. Thus, a transaction for a certain user that accesses the user's resources at the resources 162, would instead use the associated element of the resources 164 at the service provider 164.

The resources 162 can be modeled by the MT-FI 150, such as by using resource representations using the hierarchical data structure 254 that is managed by the FI-IDP 256. In some embodiments, a transaction resource manager 306 can be used to manage resource representations that are mapped to each tenant represented by the MT-ID 132. For example, the transaction resource manager 306 can be implemented as a separate wallet for the tenant/service provider 108. The transaction resource manager 306 can manage separate MT-FIs for each customer of the tenant 108.

The mt-transaction processor 101 can process transactions, such as ones indicated by the request 302. Transactions can be processed using the risk 138 and/or compliance services 140 based on identity data of the MT-ID 132 and resource data of the MT-FI 150. Once the mt-transaction processor 101 determines the appropriate identity and resources for the transaction, they can be passed to the payment core service 148. The payment core service 148 can process the transaction and use the external processing 312, such as external processors, networks (e.g., credit card networks), and/or issuers.

FIG. 4 is a diagram illustrating hierarchical data structures used by the multi-tenant software architecture systems that provide unified transaction services. FIG. 4 illustrates several hierarchical data structures 402, 403, and 404 (which collectively can be referred to as the hierarchical data structure 244), which are accessible via the MT-IDP 246. FIG. 4 illustrates the relationships between the entities of the hierarchical data structures 402-404. The organization and linking of the hierarchical data structures of FIG. 4 can be referred to as a dependency graph. It is noted that the organization and type of the hierarchical data structures 402-404 is shown for illustrative purposes only, and that one or more of 3P-IDP representations 406 and 411 can implement different data structures, as desired.

The first hierarchical data structure 402 illustrates service providers 409, 412(1), and 412(2) that are fully integrated, and thus offer core services to a merchant 418, consumer 416, lightweight merchant 420(1), as well as to entities of an on-boarded service provider that is shown by second hierarchical data structure 404. In FIG. 4, the entities 412(1), 412(2), 414(1). 414(2), 416, and 420(1) are fully integrated into the multi-tenant platform 102, and are managed by the MT-IDP 246.

The hierarchical data structure 404 can correspond to the on-boarded service provider 110 and is managed by the 3P-IDP representation 406. Thus, the 3P-IDP representation 406 can be a representation, in the hierarchical data structure 244, of the actual 3P-IDP 212 used by the service provider 110. The Identity-as-a-Service (IaaS) services can further map different schema used by the 3P-IDP 212 to the hierarchical data structure 404. During onboarding of the service provider 110, the multi-tenant platform 102 can generate representations 408(1) and 408(2) for the consumers 214(1) and 214(2) that are managed by that tenant's 3P-IDP 212. The consumers 408(1) and 408(2) are not fully integrated into the multi-tenant platform 102 (e.g., unlike consumer 416), and are instead on-boarded onto the multi-tenant platform 102. The multi-tenant platform 102 can further generate representations in the first hierarchical data structure 402 by generating linked consumers 414(1) and 414(2). A linked consumer is an entity that represents a corresponding entity in another hierarchical data structure, and that contains a limited amount of the data for that corresponding entity. The linked consumers 414(1) and 414(2) link to the consumers 408(1) and 408(2), respectively.

During the process of onboarding the service provider 108, the multi-tenant platform 102 can similarly generate the hierarchical data structure 403 that is managed by the 3P-IDP representation 411. As shown, the multi-tenant platform 102 can generate representations 432(1) and 432(2) of the merchants 206(1) and 206(2), respectively. The actual identities of the merchants 206(1) and 206(2) are managed by that tenant's 3P-IDP 204, and their representations 432(1) and 432(2) are managed by a 3P-IDP representation 411 of the tenant's 3P-IDP 204. The merchants 432(1) and 432(2) are not fully integrated into the multi-tenant platform 102 (unlike merchant 418), and are instead on-boarded onto the multi-tenant platform 102. During the on-boarding process, the multi-tenant platform 102 can also generate a lightweight merchant 420(1) that links to the merchants 432(1). A lightweight merchant is an entity that represents a corresponding entity in another hierarchical data structure, and that contains some of the data for that corresponding entity.

The hierarchical data structure 402 indicates that the linked consumers 414(1) and 414(2) are child nodes of the node of the service provider 412(1), and thus are acted upon by the service provider 412(1). However, the service provider 412(1) does not directly modify the linked to consumers 408(1) and 408(2). Similarly, the hierarchical data structure 402 indicates that the lightweight merchant 420(1) is a child node of the node of the service provider 412(2), and thus are acted upon by the service provider 412(2). However, the service provider 412(2) does not directly modify the linked to merchant 432(1). An example of this is where the merchant 432(1) is operating as merchant of a service provider indicated by the 3P-IDP representation 409, which can be a marketplace tenant. Although the lightweight merchants 420(1) can inherit any access permissions from the service provider 412(2), the 3P-IDP representation 411 provides the access to the merchant 206(1) that is represented by 432(1). In case of access permission conflict, access permissions indicated by merchants 206(1) prevails, followed by access permissions indicated by merchant 432(1), and lastly by the lightweight merchant 420(1). However, in some cases, the multi-tenant architecture 102 can be configured to change and/or propagate any access permissions of the merchant 432(1) and/or merchant 206(1) based on access permissions of the lightweight merchant 420(1).

FIG. 5 is a diagram illustrating embodiments of relationships between a multi-tenant identity service, multi-tenant transaction resource service, and multi-tenant social graph service for unified transaction services. FIG. 5 illustrates example relationships between various data structures and services used by the multi-tenant platform 102 for a particular user. FIG. 5 is described with reference to the examples shown in FIGS. 1-4 for ease of explanation.

The hierarchical data structure 244 manages the multi-tenant identity and includes the MT-IDP 246 that links to a service provider 412(1), which in turn is linked to two linked consumers 414(1) and 414(2). The hierarchical data structure 244 can include similar content to what is shown by FIG. 4, with simplifications for readability purposes. Various implementations of generating the hierarchical data structure 244 when onboarding tenants are discussed above with reference to FIGS. 1-4.

The hierarchical data structure 264 includes the SG-IDP 266 that manages the social graph connections for each user, includes the node for a user 501, as well as a connection graph 510 that indicates the social connections between other users and the user 501. The connection graph 510 shows links between various users and the order of their associations. The MT-SG domain supports a network model of users associated with tenants, where these users can be associated with MT-IDP linked consumers (i.e., that correspond to various users). Each of these users, including the user 501, can be associated with a unique resource representation (e.g., as discussed with reference to the transaction resource service). The LC 414(1) can include a user ID that corresponds to the user 501 element in the hierarchical data structure 264. The LC 414(1) can also include a resource representation that corresponds to the resource representation 502 in the hierarchical data structure 254.

The hierarchical data structure 254 includes the FI-IDP 256 that manages the resources 504-510, which can represent a portion of the resources 162 that are associated with the user. As noted above, this portion of the resources 162 can be mapped to the resources 164. This mapping can be noted by the resource representation 502. Thus, the MT-FI can model a tenant-based transaction resource manager that is associated with the consumer's representation and transaction resources. The transaction resource manager can include the associated transaction resources 504-510, which for implementation of financial instruments, can correspond to a bank, account balance, and/or types of cards (Credit, Debit, Pre-paid for the user). As shown in the diagram, the resource representation 502 can be associated with a particular tenant (i.e., the service provider 412(1) that is associated with various transaction resources including 504-510. In some implementations, the service provider 412(1) may support multiple resource representations.

The MT-SG 160 allows for managing social relationships between identities across different namespaces. As shown in FIG. 5, the user 501 can be linked, via the LC 414(1), from the hierarchical data structure 244 of the identity services 132. The hierarchical data structure 264 associated with the user 501 can indicate that the user 501 interacts with various users represented by nodes in the graph portion 510. These nodes, that can represent identities of other users in the namespace of the tenant associated with the service provider 412(1), can be derived from the MT-IDP 246. The links between the nodes of the graph portion 510 can represent various characteristics of interaction between the users. For transaction services, the interaction can be characterized with a transaction amount, a type of transaction resources used, an actual source of the transaction resource. Other such characteristics can indicate any messages exchanges, similar interests between the users, co-location, proximity, relationships (friend, spouse, family, etc.) and/or other attributes that qualify these links. Once the hierarchical data structure 244 is established, for any future interactions of the user 501, the hierarchical data structure of the MT-SG 160 can be used to build user experiences. For example, for sending actual transaction resources from the user's 501 account, the mt-transaction processor 101 can determine certain relevant receivers based on the MT-SG 160.

FIG. 6 is a flow diagram illustrating embodiments of operations for using multi-tenant software architecture systems that provide unified transaction services. The method of FIG. 6 is described with reference to the systems and components described in FIGS. 1-5 (for illustration purposes and not as a limitation). The example operations can be carried out by the transaction processor that uses the multi-tenant platform 102.

Beginning with 602, the processing system 100 receives a request at a first provider to provide a service to a user. The first provider can be a service provider 208 that is on-boarded by the multi-tenant platform 102, and thus can provide on-boarded services to the users via the multi-tenant platform 102. In some embodiments, the request can be received by the actual service provider, such as by the service provider 108 (as illustrated by FIG. 3). The request can be for a transaction service that is provided by the onboarded service provider. The transaction service can be for transaction resources that appear to be a part of the service provider 108, but are actually hosted by another service provider, such as by the service provider 164. In some embodiments, the multi-tenant platform 102 can receive the request from the user device 104 for a transaction that appears to be provided by the multi-tenant platform 102 and that uses resources that appear to be hosted by the multi-tenant platform 102. The actual service that provides the requested transaction can be performed by another certain service on the multi-tenant platform 102 for a fully on-boarded service provider, or can be performed by another service at another service provider that isn't fully on-boarded.

At 604, the multi-tenant platform 102 accesses a representation of the first service provider in a first hierarchical data structure that is managed by the second service provider. With reference to FIG. 4, the multi-tenant platform 102 can access the hierarchical data structure 403 that represents the actual service provider 108, where the hierarchical data structure 403 is managed by the MT-IDP 246. With reference to FIG. 5, the multi-tenant platform 102 can access the LC 414(1) in the hierarchical data structure 244 that is managed via the MT-IDP 246. The multi-tenant platform 102 can also access the LC 506 in the hierarchical data structure 254 that is managed via the FI-IDP 256.

At 606, the multi-tenant platform 102 determines whether the transaction resource for the transaction is available at the second service provider using a resource representation. At 606, the multi-tenant platform 102 can first determine the transaction resource needed for the requested transaction. The multi-tenant platform 102 can determine whether the transaction resources corresponding to the resource representation are accessible via the first service provider or the second service provider. The multi-tenant platform 102 can determine that the transaction resources required for completion of the first transaction service are accessible at the second service provider based on the request which can indicate one or more of a type and a source of the transaction resources. The multi-tenant platform 102 can determine whether a second hierarchical data structure, that is managed by the first transaction service, includes one or more transaction resources that are linked with the first representation in the first hierarchical data structure. The multi-tenant platform 102 can, responsive to determining that the second hierarchical data structure does not include the one or more transaction resources that are linked with the first representation, generate the resource representation at the second resource provider without linking to the first resource provider. If the transaction resource is available at the second service provider, flow continues to 610. Otherwise, flow continues to 608.

At 608, the multi-tenant platform 102 determines which service provider provides the transaction resource. For example, the determination is for whether the transaction resource is one of the core services 130(1) available at the multi-tenant platform 102 (acting as the first service provider), or is a service that is provided by another service provider (also referred to as a “requested service provider”).

At 610, the multi-tenant platform 102 determines whether the transaction resource is accessible at the provided service provider via the resource representation. The multi-tenant platform 102 can determine that the required transaction resources are accessible via the resource representation based on determining that a second hierarchical data structure, that is managed by the first transaction service, includes the one or more transaction resources that are linked with the first representation in the first hierarchical data structure. For example, the multi-tenant platform 102 can determine that additional user information (for the user and/or the second service provider) that is needed to access the service is not available at the first hierarchical data structure. For example, the multi-tenant platform 102 can determine certain user data from the representation in the first data structure, but also determine that additional user information is needed to perform the service. If the user data is available at another service provider, flow continues to 612. Otherwise, flow continues to 616.

At 612, the multi-tenant platform 102 determines a service provider through which the transaction resource can be accessed via the resource representation at the provided service provider. For example, with reference to FIG. 3, the mt-transaction processor 101 can determine that the resources 164 (at the service provider 110) can be accessed via the resources 162 (at the service provider 108). In some embodiments, the multi-tenant platform 102 can determine to use another transaction processor instead of the mt-transaction processor 101. For example, the multi-tenant platform 102 can determine to use another transaction processor of the service provider 110 for processing (including accessing of the resource representation discussed below). The other transaction processor can be modelled as a representation transaction processor by the multi-tenant platform to facilitate access of the actual transaction processor at the service provider 110.

At 616, the multi-tenant platform 102 accesses, at the appropriate service provider, the transaction resource using the resource representation. The multi-tenant platform 102 can use the mt-transaction processor 101 to access the transaction resources 164 at the first service provider 110 via the resource representation. The mt-transaction processor 101 can be configured to route the first transaction service with reference to the transaction resource 164 through additional services, such as services 138, 140, and/or 312. In some embodiments, as discussed above, the multi-tenant platform 102 can use, via the representation of the service provider, the actual transaction processor of the service provider 110 to access the transaction resources 164 at the first service provider 110 via the resource representation.

The multi-tenant platform 102 can determine a user representation of the user at third service provider, the third service provider modeling a social graph of connections between the user and a plurality of users. The multi-tenant platform 102 can process the first transaction service using the social graph. The third service provider can be accessible, at the first service provider, via the second service provider using the first representation. The multi-tenant platform 102 can generate a resource request for consuming a first amount of transaction resources, via the resource representation, for the first transaction service. With reference to FIG. 3, the transaction processor 101 can generate a resource request to access the transaction resource 164 at the service provider 110.
